316 Stainless Steel or Titanium, and are available in both Sealed and Mag-drive configurations. These pumps feature Helical gears and relieved wear plates for smoother and quieter operation and intrinsic reduction of gear separation forces. Their unique and durable design will assure extended life in high-pressure pumping applications.

*ANSI 150# Flanges are standard; 300# RF Flanges are optional.
** For flanged pumps, pressure derating is required based on flange type and temperature.
